采用配置RRHT 柱的1200 快速高分离度液相色谱(RRLC)系统快速分析橡胶中化学抗降解剂
Abstract:
采用液相色谱-紫外/可见光检测器，基于ASTM D5666-95 方法概要，开发了一种最优测定橡胶中抗降解剂p-苯二胺(PPD)及它的相似物的方法。使用配备ZORBAX 1.8 μm RRHT (Rapid Resolution High Throughput) 柱的Agilent 1200 RRLC 系统，一次运行5 种PPDs 总的分析时间大约比传统 5 μm 柱子方法快6.4 倍。
p-Phenylenediamine (PPD), a chemical antidegradant for rubber, and its analogs were found to be optimally determined using liquid chromatography with ultraviolet/visible detection according to the guidelines of ASTM Method D5666. Using the Agilent 1200 RRLC system with ZORBAX 1.8-μm columns, the PPDs could be separated in one run with a total analysis time up to 6.4 times faster than the conventional method based on a 5-μm column.
